more boost with less throttle

[justryan]

im new to turbo cars so this may be dumb but i know my car it trifecta tuned today i had my boost gauge hooked up and at full throttle it get about 16-17 psi and about 1/2 i average about 20. is this normal.

You're meeting your WOT max torque demand at a lower boost level then part throttle.

cool thanks.

Because inquisitive minds want to know.

It seems as if max torque is the limiting factor with our RS engines. I am sure this is to protect other hardware! So what is the weak link?
Transmission, bottom end of 1.4 or some other component.

I've heard of people going through clutches and transmissions but I haven't heard of someone popping a 1.4 yet. If there has been its very few.

 

[justryan]

so max torque cant be removed with tuning? but why does it seems quicker with less throttle?

There's a couple different ways you can tune. You can tune so that the limiting factor is desired TQ, or you can set TQ numbers high and have the limitation being a specific boost value.

With TQ being the limiting factor you'll have consistent power in nearly any condition, with TQ not being the limitation you may have significantly more power on cool days and much less on hot days.

It's just how the tuner decides to tune.
